Struct rustc_index::bit_set::SparseBitSet
source · Expand description
A fixed-size bitset type with a sparse representation and a maximum of
SPARSE_MAX
elements. The elements are stored as a sorted ArrayVec
with
no duplicates.
This type is used by HybridBitSet
; do not use directly.

sourcepub fn union<Rhs>(&mut self, other: &Rhs) -> boolwhere

pub fn union<Rhs>(&mut self, other: &Rhs) -> boolwhere
Self: BitRelations<Rhs>,
Sets self = self | other
and returns true
if self
changed
(i.e., if new bits were added).

Self: BitRelations<Rhs>,
pub fn subtract<Rhs>(&mut self, other: &Rhs) -> boolwhere
Self: BitRelations<Rhs>,
Sets self = self - other
and returns true
if self
changed.
(i.e., if any bits were removed).
sourcepub fn intersect<Rhs>(&mut self, other: &Rhs) -> boolwhere
Self: BitRelations<Rhs>,
pub fn intersect<Rhs>(&mut self, other: &Rhs) -> boolwhere
Self: BitRelations<Rhs>,
Sets self = self & other
and return true
if self
changed.
(i.e., if any bits were removed).

Layout§
Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
